Abstract (en)
This application relates to the field of motor technologies, and in particular, to a method for improving a heat dissipation capability of an oil-cooled motor, insulation paint, and a method for manufacturing the insulation paint. The method includes: performing insulation processing on a motor component by using insulation paint, where the motor component includes a stator winding and/or a rotor winding; and installing the motor component undergoing the insulation processing into an oil-cooled motor, where a basic component of the insulation paint is unsaturated polyesterimine modified by using an inorganic layered silicate. The insulation paint has high heat conductivity, high heat resistance, and low viscosity, and therefore can improve a heat dissipation capability of the oil-cooled motor in a use process, and reduce a temperature rise of the oil-cooled motor in the use process, thereby improving power of the oil-cooled motor and prolonging a service life of the oil-cooled motor.
